CVE-2024-50101

  2. Vulnerabilities (CVE)
  3. CVE-2024-50101
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Fix incorrect pci_for_each_dma_alias() for non-PCI devices Previously, the domain_context_clear() function incorrectly called pci_for_each_dma_alias() to set up context entries for non-PCI devices. This could lead to kernel hangs or other unexpected behavior. Add a check to only call pci_for_each_dma_alias() for PCI devices. For non-PCI devices, domain_context_clear_one() is called directly.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: iommu/vt-d: Se corrige pci_for_each_dma_alias() incorrecto para dispositivos que no sean PCI Anteriormente, la función domain_context_clear() llamaba incorrectamente a pci_for_each_dma_alias() para configurar entradas de contexto para dispositivos que no sean PCI. Esto podría provocar bloqueos del kernel u otro comportamiento inesperado. Agregue una verificación para llamar solo a pci_for_each_dma_alias() para dispositivos PCI. Para dispositivos que no sean PCI, se llama a domain_context_clear_one() directamente.
